Abstract

Pump for automotive windshield washing installation, which includes an animated pumping element of a reciprocating movement contained in a pump casing and which performs its suction stroke under the action of a subatmospheric pressure generated in the pump casing and against the action of a spring, said spring realizing the discharge stroke of the pumping element when the space containing said spring communicates with the ambient atmosphere through a valve, which puts said space in communication with the ambient atmosphere when a switch that includes a movable switch body that supports a switching element for controlling the operation of the wiper motor is placed in a position in which said motor is operating, characterized in that the space containing said wharf is arranged so that it can be connected to a source of subatmospheric pressure by means of a check valve ion, said switch body being arranged so that it is possible to rotate it without opening the valve that puts said space in communication with the ambient atmosphere, giving rise to a traction force exerted on the body of the switch to which the valve serves to put in communication said space with the ambient atmosphere is opened, being the resistance that opposes the circulation of gas through the conduit that puts in communication the ambient atmosphere with the space of the crankcase of the pump containing said spring, lower than the resistance which opposes the circulation of gas through the conduit connecting said space with the source of subatmospheric pressure.
